I'm still using the last version of iView MediaPro before MS bought it. Works great even for the 5DII movie files. You can play them, keyword, star, rename everything just like still photos. A visual database that is searchable is far easier than just a text database. We are visual artists.

But can it handle offline HDs

Im shooting a TB a month or so now so any online (ie on my network or the web) solution is a little costly

Sony Picture Motion Browser (PMB) is surprisingly good for OEM software. It is dedicated to AVCHD files though. For more common files (MOV, AVI, Etc.) many common photo browsers do a good job. I've used ACDSee, Windows Live Photo Gallery and Picasa with good success.
